摘要
对某地区医疗建筑、办公建筑和酒店建筑的0.4 kV配电网络的抽样检测测量数据进行分析,介绍了相关建筑物低压配电系统的谐波分布情况。分析了各种谐波的形成机理,并提出了减少或抑制谐波产生的方案,同时对多谐波源的叠加估算方法进行了探讨,为配电系统谐波综合治理提供了科学依据。
The 0.4 kV power distribution network sampling inspection measurement data of medical buildings, office b,ildings and hotel buildings in some area were analyzed, to nnderstand harmonic distribution of low voltage power distribution system of relevant building. The formation mechanism of various harmonic was analyzed, and seheme tot reduce or suppress harmonics was proposed. The superposition estimation methods of multiple harmonic source were discussed. It could provide a scientific basis for the comprehensive management of the power distribution system harmonies sttppressJon.
